Abstract: The affinity of the LDE-type flare locations to the reversed coronal magnetic sectors (and their boundaries) is studied. The Sun's gradual magnetic reversal (as described by computed coronal field structures) is compared with the occurrence of a flare activity in the solar unipolar coronal magnetic sectors. It is shown that the active regions of the 21st and 22nd cycles, giving rise to the LDE-type flares, are concentrated in the sectors of reversed magnetic polarity.
